A new, very impressive cotton planting conditions calculator has been created by Dr. Guy Collins and Dr. Keith Edmisten with help from the Climatology Office at North Carolina State University. In this post, I highlight a few of the features and provide an example of how the calculator works.

Nothing crazy but much of the wheat is still in the milk stage and would be susceptible to excessive defoliation. Occasionally, armyworms may even cut the heads, typically when populations are high. Yield loss is most likely if defoliation occurs during the milk stages, with Continue reading
Wheat is in bloom and when considering a fungicide application one needs to assess their risk for fusarium head blight (FHB) or head scab infection. Continue reading
DRIER CONDITIONS BOOST PLANTING
Drier conditions allowed farmers back into the field on a limited basis. Corn, soybean, and cotton planting continued. Strawberry harvest and the first cutting of hay began. Winter wheat responded well to the warmer, drier weather, as did pasture and forage conditions. There were 4.7 days suitable for fieldwork last week. Topsoil moisture rated 73 percent adequate, and 27 percent surplus. Subsoil moisture rated 1 percent short, 71 percent adequate, and 28 percent surplus. Hay and Roughage Supplies rated 16 percent very short, 25 percent short, 52 percent adequate, and 7 percent surplus. Continue reading at TN Crop Weather 04_29_19.
